LDAR Services for Oil and Gas Operators

LDAR stands for Leak Detection and Repair. It is a program used to find, document, repair, and verify leaks from equipment such as valves, connectors, tanks, compressors, and piping. In oil and gas operations, LDAR commonly focuses on methane and volatile organic compound emissions, with procedures designed to support environmental performance, operational reliability, and applicable reporting obligations.

In oil and gas, LDAR means Leak Detection and Repair. The term describes the full workflow of detecting emissions or vapor leaks, validating the source, documenting the event, dispatching repair resources, completing the repair, and confirming the outcome. Continuous LDAR monitoring can add visibility between conventional periodic surveys by identifying validated fugitive events as they occur.

Continuous LDAR monitoring uses permanently deployed sensing and software to watch wellsite equipment around the clock. Well Checked combines long-wave infrared optical gas imaging, high-resolution video, and acoustic sensing with AI-assisted analysis. Zentinal Core™ filters known non-fugitive process activity and validates anomalies, then sends near-real-time alerts through the dashboard, email, text, or connected SCADA workflows.

Well Checked’s LDAR offering is designed for continuous methane and VOC leak detection at upstream oil and gas sites. Long-wave infrared optical gas imaging provides gas-focused observation, while video and acoustic intelligence add operating context. This multi-sensor approach helps distinguish potential fugitive emissions from expected equipment activity, supporting a more focused investigation and response process.

Well Checked structures its data output to support alternative-monitoring compliance submissions under EPA methane rule 40 CFR Part 60 Subpart OOOOb. Zentinal IQ™ quantifies emissions after Zentinal Core™ has validated an event, helping create a more defensible record. Operators remain responsible for determining the applicable rule requirements and submitting their compliance documentation to the appropriate authority.

Once Zentinal Core™ validates a fugitive gas event, the operator’s designated dispatch team can receive near-real-time alerts through the Well Checked Dashboard, email, text, and SCADA. Well Checked also provides response-workflow templates, dispatch runbooks, and rapid-response protocols designed to support acknowledge, dispatch, and mitigate actions within 24 hours when site conditions and operator resources allow.

Continuous monitoring is designed to reduce unnecessary routine site visits and provide visibility between periodic inspections, not to eliminate every field task. Operators still need personnel for repairs, safety-critical work, regulatory duties, and conditions requiring onsite confirmation. By validating events and prioritizing exceptions, the platform helps teams direct field resources toward sites where action is most needed.

Yes. Well Checked offers SCADA integration services that place Zensory.ai™ alerts, emissions information, and operational insights inside existing control-room workflows. Integration can help teams receive validated event notifications without relying on a separate monitoring process. Configuration is tailored to the operator’s existing environment, escalation rules, communication pathways, and preferred response procedures.
